A regulator 42, Figs. 4 and 5, is mounted in the Fig. 5 is a longitudinal sectional view of the bore 36 of the nozzle head 21, Fig. 4, and said regulator of Fig. 4. regulator 42 includes a sleeve 43 having its upper Fig. 6 is an outer or upper end view thereof. or outer portion slit longitudinally as at 44 and Fig. 7 is an inner or lower end view of the provided with a flared tapered end 45 to fit the same. seat 31. The segments produced by the slits are contracted as the sleeve is pulled inward and due to an inherent resiliency they will spring apart or expand as the sleeve is moved outward. The sleeve bore 43a runs from end to end and through the exteriorly threaded reduced stem 46.

On said stem 46 is screwed the adjusting member 41 having a bore 48 running through it from end to end and of two different diameters, the larger diameter having a thread for engagement with the threaded stem 46. According to the showing in Fig. 5, a downwardly tapering collar 49 is formed on the adjusting member near its outer or lower end, providing a conical surface for coaction with the seat 32 and a shoulder 59 to engage the shoulder 35. The extreme lower or outer end of said adjusting member has a non-circular portion 51 for the reception of a tool by which the adjusting member may be rotated.

From the foregoing it will be obvious that by separating the head section 27 from the body section 26 and then turning the adjusting mem ber 41 in the proper direction the sleeve will be pulled inward or allowed to move outward and thus regulate the size of the bore After the sleeve 43 has been adjusted, the tip or another somewhat similar one, is screwed down until its end wall engages the outer end of the sleeve.

The provision of demountable and interchangeable tips besides enabling the operator to change from the use of one gas to another by merely substituting tips also makes it possible to manufacture the nozzle from one metal, such as brass, and utilize another metal, such as copper, for the tips.

Of course I do not wish to be limited to the exact details of construction herein shown and described as these may be varied within the scope of the appended claims without departing from the spirit of my invention.

Having described my invention what I claim as new and useful is:

1. A nozzle for gas burning apparatus comprising a head section provided with a bore therethrough from an outer end to an inner end thereof, an outwardly flared tapered interior seat at the outer end of said head section, means forming a socket at the inner end of said head section and larger than the bore, a shoulder within said socket, a tubular sleeve having a tapered outer end to fit the tapered seat and provided with a plurality of slits crosswise of said sleeve and extending longitudinally thereof for a predetermined distance from said outer end to produce segments, hollow means having threaded engagement with the sleeve and engaging the shoulder to pull said sleeve inwardly when the hollow means is rotated in one direction, and a body section having a bore therethrough from end to end thereof and detachably connected to the inner end of the head section.

2. A nozzle for gas burning apparatus comprising a head section provided with a bore therethrough from an outer end to an inner end thereof, an outwardly flared tapered interior seat at the outer end of said head section, said outer end of the head section being externally threaded, means forming a socket at the inner end of said head section and larger than the bore, a shoulder within said socket, a body section having a bore therethrough from end to end thereof, a neck carried by the body section for engagement with the socket end of the head section to detachably connect said sections, a conical seat on the interior of the outer end of the neck, a sleeve having a tapered outer end to fit the tapered seat and provided with a plurality of slits crosswise of said sleeve and extending longitudinally thereof for a predetermined distance from said outer end to produce segments, a hollow adjusting member having threaded engagement with the sleeve, a tapered collar on said adjusting member to fit the tapered seat in the neck of the body section and producing a shoulder to engage the shoulder formed in the socket so that when said adjusting member is rotated in one direction the sleeve will be pulled inwardly, and an apertured tip removably mounted on the threaded outer end of the head section.

3. In a nozzle for gas burning apparatus including a body section and a head section detachably connected together and each having a bore therethrough from an outer end to an inner end thereof, said head section having an outwardly flared tapered interior seat at the outer end thereof, a regulator within said nozzle and comprising a sleeve having an outwardly flared outer end to engage the seat and provided with a plurality of slits crosswise of said sleeve and extending longitudinally thereof a predetermined distance from said outer end to produce several segments having an inherent resiliency to normally separate them, and a hollow adjusting member threadedly connected to the sleeve and held against longitudinal movement in the nozzle to pull the sleeve inwardly for drawing the segments together as they move along the seat.
